If Rush Limbaugh wants the audience to believe his apology to Sandra Fluke is sincere, he might want to avoid insulting young women every chance he gets. Barely a day after issuing his “heartfelt” apology towards Fluke–whom he called a ‘slut’ and a ‘prostitute’–Limbaugh was taking umbrage with another young woman: Tracie McMillan.

What did Tracie McMillan do to earn Limbaugh’s ire? Aside from writing a rather innocuous sounding book about the relationship between food and class, McMillan appears to have annoyed Rush because she’s single, she’s smart, and people are listening to what she has to say.

“What is it with all these young, single, white women? Overeducated doesn’t mean intelligent,” The Raw Story quoted Limbaugh as saying. Forbes continues the quote, straight from the official transcript: “For example, Tracie McMillan, the author of this book, seems to be just out of college and already she has been showered with awards, including the 2006 James Aronson Award for Social Justice Journalism.”

With this attack on MacMillan, Limbaugh has hit a bigotry trifecta: it’s misogynistic, classist, and anti-intellectual.

Rush Limbaugh is already losing advertisers left and right thanks to his boorish commentary on female sexuality. Now he’s decided women shouldn’t be educated, either. Can it be only a matter of time before the words “barefoot” and “pregnant” come out of his mouth?

At a time when what it means to be female in America is at the forefront of political discussion, how badly are Limbaugh’s missteps going to hurt those who seem to be on his side going into the election?
